Millimeter work planned
India launches European solar research satellites into space

The solar corona is only visible during a total solar eclipse - and for a few minutes. An ESA mission wants too change that and has to do millimeter work to achieve this.
The European Space Agency (Esa) has sent two satellites into space to demonstrate precise formation flight. The mission, called “Proba-3“, is intended to provide insights into the solar corona, which is difficult to see, and at the same time serve to prepare for similar projects with several satellites in the future.
A day later than planned, a launch vehicle from the Indian space agency Isro with the European satellites on board lifted off from the Satish Dhawan Space Centre on the southeast coast of India at midday.
The start was accomplished, the Esa announced on the X platform. The satellites have been placed in their intended orbit, she quoted Radhakrishnan Durairajden, head of Isro’s commercial arm, as saying.
“Proba-3” is a exhibition mission. Scientists expect to obtain substantially more data about the corona – the sun’s outer atmosphere - using the technology used in the project. For the first time, the satellites will fly through space in a formation flight with millimeter precision in relation to each other.
To achieve this,the pair of spacecraft will be separated in space at the beginning of next year.The spacecraft will then move around the Earth in a large,elliptical orbit. The closest distance of the orbit to Earth is 600 kilometers, the furthest point is about 60,000 kilometers away.
“Around the top of its orbit, the Proba-3 occult spacecraft will cast a precisely controlled shadow on the coronagraph spacecraft, approximately 150 meters away, to produce solar eclipses as needed for six hours,” Esa said. There was no other way to simulate a solar eclipse.
The corona is usually only visible during a total solar eclipse because of the sun’s radiant and blinding light. This happens when the moon blocks out the sun’s light for the part of the Earth that is in its shadow. On Earth this is only the case for a few moments.
“Proba-3” could deliver the first images of the solar corona in March. Four ESA countries are involved in the two-year mission, including austria and Switzerland.
